The main parts of the most usual type of valve are the body and the bonnet. These two parts form the casing that holds the fluid going through the valve. 1A. DAVINCI VALVES _ BODY is the primary pressure-retaining component of a valve. It forms the external casing that contains all internal parts (known as the trim) and defines the flow path geometry. Mechanically, it must withstand internal pressure, temperature, and external stresses while maintaining structural integri

A valve is a mechanical device whose primary function is to regulate, direct, or control the flow of a fluid whether gases, liquids, or multiphase mixtures—by means of opening, closing, or partially restricting one or more flow passages. Although valves are technically classified as fittings within piping systems, their importance warrants treating them as a distinct engineering category. Under normal operating conditions, when a valve is open, fluid flows naturally from a re
